What Kind of Fabric Is On This Chair?

Q: I need help identify a fabric on an upholstered chair I saw in Elle Decor a few months ago. It has a sort of freeform chevron pattern in what appears to be a dark gray and off-white colorway. If not this fabric, perhaps someone could suggest a similar alternative for less than $70 per yard? Must be an upholstery weight fabric and I do prefer the gray and white combo.
